I thinking is that if the external WG spikes, the internal one on the turbo should vent that spike assuming both are set to the same PSI.
Is this logical or have other people done this?
Thanks.

1. Improper placement - the wastegate should be placed as close as possible to the turbo outlet flange - like at a collector.
2. with a T-3 or similar turbo the hole where the internal wastegate flapper was engineered...isn't normaly used.
this is the best setup if you can't center the wastegate.
plus this way you have a larger overall outlet for the downpipe. It is over 3" with wastegate open!
